Community survey special field

Hi,

i need to create a question with :

- user can add infinite line of answer.

- each answer has a second column with a dropdown answer.

Example :

1. add infinite line like frame 2 (this to add participants to the past event).
2. line who is added when you click to add a child button.
3. simple text field.
4. dropdown answer with predefinited answer.

The idea is to provide the possibility to the participants to an event to provide feedback about the event.
So participants 1 : name - your feedback : good, not good, ...

If it's not possible, any idea how i can do such thing ?

Thanks !
